Chapter 1 Product Overview
Route Processors
For example, when the boot field of the software configuration register is set to
0x0 and you press the NMI switch, the GRP remains at the ROM monitor prompt
(rommon>) and waits for a user command to boot the system manually. If the boot
field is set to 0x1, the system automatically boots the first Cisco IOS image found
in the onboard Flash memory SIMM on the GRP.
Caution
The soft reset (NMI) switch is
not
a mechanism for resetting the GRP and
reloading the IOS image. It is intended for software development use. To prevent
system problems or loss of data, use the soft reset switch only on the advice of
Cisco service personnel.
Access to the soft reset switch is through a small opening in the GRP faceplate.
To press the switch, you must insert a paper clip or similar small pointed object
into the opening.
PCMCIA Slots
The GRP has two PCMCIA slots. Either slot can support a Flash memory card or
an input/output (I/O) device, as long as the device requires only +5.2 VDC. The
GRP supports only Type I and Type II devices. It does not s3.3 VDC
PCMCIA devices. Each PCMCIA slot has a button to eject the PCMCIA card
from the slot.
Asynchronous Serial Ports
The console and auxiliary ports on the GRP are asynchronous serial ports used to
connect external devices to monitor and manage the system. (See
Figure 1-4
.)
The console port is an Electronics Industries Association/Telecommunications
Industry Association (EIA/TIA)-232 receptacle (female) that provides a data
circuit-terminating equipment (DCE) interface for connecting a console terminal.
